Palm Desert High School’s Charlie Reiter added another tournament to his already business summer schedule Thursday, and this time the tournament is the most important amateur champions in the country.

Reiter, who will be a senior at Palm Desert this fall, fired and stunning opening round and then survived a difficult second round Thursday to earn a berth into the U.S. Amateur Championship to be played next month at Riviera Country Club in Pacific Palisades.

Reiter finished second in the Amateur qualifying event at Rope Rider Golf Club in Cle Elum, Wash. That was good enough for Reiter to earn one of three berths into the Amateur tournament from the 78-player field.

Earlier this summer Reiter, 17, earned a berth into the U.S. Junior Amateur tournament to be played this month in Kansas.

Reiter started Thursday’s 36-hole qualifier in electrifying fashion, playing his first six holes in 5-under including a hole in one on the 155-yard 11th hole, Reiter’s second hole of the day. He finished the morning round with a 7-under 65 including a bogey on his final hole to take a four-shot lead into the afternoon.

But Reiter’s lead quickly disappeared in the afternoon when he shot a 4-over 40 on the front nine of the Rope Rider course with six bogeys and two birdies. On the back nine Reiter added three birdies and three bogeys, giving him a nine bogeys in the afternoon. But the 76 in the final 18 holes still gave Rieter a 3-under 141 total, one shot behind medalist Chris Crisologo of Canada and two shots clear of a playoff for the third and final berth into the Amateur finals.

The Amateur will be played August 14-20 at Riviera Country Club, the home of the PGA Tour’s Genesis Open.
